“…There are presently few omics studies of drought in date palm ( Table 1). A recent proteomics study identified genes involved in salt and drought tolerance in P. dactylifera (Rabey et al, 2016). The researchers challenged 3-month seedlings of the 'Sagae' cultivar with polyethylene glycol (82.5 g/L) and salinity (43 g/L) and identified 47 differentially expressed genes in the leaves.…”

Date palm (Phoenix dactylifera L.) is a socioeconomically important crop in the Middle East and North Africa and a major contributor to food security in arid regions of the world. P. dactylifera is both drought and salt tolerant, but recent water shortages and increases in groundwater and soil salinity have threatened the continued productivity of the crop. Recent studies of date palm have begun to elucidate the physiological mechanisms of abiotic stress tolerance and the genes and biochemical pathways that control the response to these stresses. Here we review recent studies on tolerance of date palm to salinity and drought stress, the role of the soil and root microbiomes in abiotic stress tolerance, and highlight recent findings of omic-type studies. We present a perspective on future research of abiotic stress in date palm that includes improving existing genome resources, application of genetic mapping to determine the genetic basis of variation in tolerances among cultivars, and adoption of gene-editing technologies to the study of abiotic stress in date palms. Development of necessary resources and application of the proposed methods will provide a foundation for future breeders and genetic engineers aiming to develop more stress-tolerant cultivars of date palm.

“…El Rabey et al 4,5 analyzed the proteome of date palm under drought and salinity stress condition and defined the genes responsible for drought and salinity tolerance. The response of date palm seedling against drought stress exerted by treatment with three levels of poly ethylene glycol at four-time points ( 0, 1, 3, 7 days) was studied in the light of phenolic and flavonoid content and the enzymatic activity of catalase, peroxidase and polyphenol oxidase.…”

Objective: the present research was focused to evaluate the date palm resistance to osmotic stress exerted by three concentrations of poly ethylene glycol 6000 in three months seedlings as reflected by the change in phenolic and flavonoid content and the activity of catalase, peroxidase and polyphenol oxidase. Materials and Methods: The phenolic and flavonoid content and the target enzyme's activity was estimated at four time points; 0,1,3,7 days. Results and Discussion: The phenolic and flavonoid content as well as the activity of catalase, peroxidase and polyphenol oxidase were increased by increasing the poly ethylene glycol and the treatment period. Conclusion: Phenolic and flavonoids are non-enzymatic antioxidants with high scavenging potential to the free radical produced from the oxidative stress resulted from the drought tolerance in date palm seedlings. In addition, the increase in the enzymatic activity of catalase, peroxidase and polyphenol oxidase under drought stress is very important to get rid of the free radicals and the reactive oxygen species.

“…In comparison, polyethylene glycol induced drought stress resulted in only 3 and 6 spots with higher and lower protein abundance, respectively. 115 Proteins involved in photosynthetic assimilation and protein synthesis declined in Chardonnay and Cabernet Sauvignon grapevines under water deficit and salinity stresses. Several proteins up regulated in tolerant cultivar Chardonnay were of an unknown function compared to Cabernet Sauvignon where proteins involved in protein metabolism were upregulated.…”

Food and nutritional security of a burgeoning global population in face of unabated land degradation, depletion of fresh water and prime croplands, and climate change impacts remains a challenge. Salinization of agricultural lands caused by the natural and anthropogenic factors a severe obstacles to realizing sustainable agricultural production. Majority of the fruit crops are highly susceptible to salinity and related problems like water logging. Use of salt tolerant scion and rootstock cultivars is seen as a viable means of lessening the salt induced damages. Nonetheless, development and commercial release of salt tolerant cultivars in fruit crops has progressed rather slowly. Moreover, salt tolerance of most of the currently available cultivars breaks down when root zone salinity exceeds the critical threshold. This has led to a departure from conventional screening trials to molecular and genomics tools to broaden the understanding of salt stress regulation at the gene, protein and metabolite levels. The ultimate aim is to introgress such genes into established cultivars in a manner that is cost efficient and safe from human and environmental health perspectives.
